Packaged Game Crashes

My Game runs fine in editor. i can package fresh projects and launch them from the editor with no problems.
Iv seen some similar posts and a log file was requested below is a paste from the end of the file starting just before what i think is the crash point.

Have you checked HUDTest1?, thats where the error points at.

I am no expert but it seems it is leaking memory somewhere? maybe you are initializing something in a loop?

Thanks im looking in to your suggestion as best i can ill let you know how i get on.
